What are the ceramic components that Macor can process

---

Macor is a high-performance machinable ceramic material developed by Corning in the United States. It combines the excellent performance of ceramics with the machinability similar to metals, and is widely used in precision instruments, semiconductors, aerospace, medical equipment and other fields. The main feature of Macor is that it can perform precision machining on conventional machining equipment such as lathes, milling machines, and drilling machines, without relying on expensive special machining methods such as laser cutting or electrical discharge machining like traditional ceramics.

The main components of Macor
Macor is a glass ceramic composite material, whose chemical composition mainly includes:
(1) Basic components
-Fluorophlogopite (KMg ∝ (AlSi ∝ O ₁₀) F ₂) (approximately 55%)
-Provide machinability to enable materials to be cut with ordinary cutting tools.
-Borosilicate Glass (approximately 45%)
-Provide high strength, heat resistance, and chemical stability.
(2) Other trace components
-Aluminum oxide (Al ₂ O3)
-Enhance mechanical strength and wear resistance.
-Magnesium oxide (MgO)
-Improve thermal stability and insulation performance.
-Silicon dioxide (SiO ₂)
-Enhance chemical inertness and corrosion resistance.

Characteristics of Macor
Due to its unique composition, Macor has the following excellent properties:
(1) Processability
-Precision machining can be carried out using ordinary metal processing equipment (such as turning, milling, drilling, tapping, etc.) without the need for special processes.
-The surface finish after processing is high, reaching Ra 0.8 μ m.
(2) High temperature resistance
-Maximum continuous use temperature: 800 ° C (short-term up to 1000 ° C).
-Low thermal expansion coefficient (9.3 × 10 ⁻⁶/° C), suitable for high temperature environments.
(3) Electrical insulation
-High dielectric strength (40 kV/mm), suitable for high-voltage insulation components.
-Low dielectric constant (6.1 at 1 MHz), suitable for high-frequency electronic devices.
(4) Chemical stability
-Acid and alkali resistant, organic solvent resistant, suitable for corrosive environments.
-Non absorbent, good air tightness, can be used in vacuum systems.
(5) Mechanical performance
-Bending strength: about 90 MPa
-Compressive strength: approximately 345 MPa
-Hardness: Mohs hardness of 5.5, between aluminum and steel, easy to machine but sufficiently wear-resistant.

Macor’s application areas
The excellent performance of Macor has made it widely used in multiple industries:
(1) Semiconductor and Electronics Industry
-Used for wafer processing fixtures, insulation supports, and vacuum sealing components.
-Suitable for high-precision electronic packaging, avoiding metal contamination.
(2) Aerospace
-Used for high-temperature sensor housings and rocket nozzle insulation components.
-Lightweight and heat-resistant, replacing some metal materials.
(3) Medical equipment
-Used for MRI equipment components, X-ray windows, and surgical instruments.
-Good biocompatibility and no risk of metal ion release.
(4) Research and Industrial Equipment
-Used for vacuum chambers, laser equipment brackets, and precision measuring instruments.
-It can maintain stability in both ultra-low temperature (liquid nitrogen environment) and high temperature environments.

What problems can Macor solve?
The emergence of Macor has solved the limitations of traditional ceramic and metal materials in certain applications:
(1) Replace traditional ceramics
-Traditional ceramics such as alumina and silicon nitride have extremely high hardness and are difficult to process, while Macor can be processed using ordinary machine tools to reduce production costs.
(2) Alternative metals
-Metals are prone to deformation at high temperatures, while Macor is heat-resistant and insulating, making it suitable for the electronics and aerospace industries.
-Metals may cause electromagnetic interference, and Macor is an excellent insulator.
(3) Replace plastic
-Plastic has poor temperature resistance (usually<200 ° C), while Macor can be used for a long time at 800 ° C.
-Plastic is prone to aging, and Macor has higher chemical stability.

Macor is a machinable ceramic composed of fluorite mica and borosilicate glass, which has excellent high temperature resistance, electrical insulation, chemical stability, and ease of processing. It is widely used in the semiconductor, aerospace, medical, and scientific research fields, solving the problems of traditional materials in precision machining, high-temperature environments, and insulation requirements.
Due to its unique composition and properties, Macor has become an indispensable functional material in high-end manufacturing.
